Question

Is gaivanised iron become rust when dip in soution of salt?

Answer 1

Current flows more easily in salt water than it does in fresh water. This is because salt water, an electrolyte solution, contains more dissolved ions than fresh water, meaning electrons can move more easily. Since rusting is all about the movement of electrons, iron rusts more quickly in salt water than it does in fresh water. Certain metal objects that spend a lot of time submerged in salt water, such as boat engines, rust quickly. However, objects do not have to be completely submerged in salt water for this to happen because increased moisture in the air and salt spray can provide the electrolyte's cation (positive ions) and anions (negative ions).
